- of which the following is a i'znll,.clear,, andexact description,whenv taken. in connection with the accompanying drawings v Thisinvention relates to temperature con.-

trolling, valves, and; more particularly to that class of valves in.which by means of a. single valve stem a plurality of valves; areoperated so that from, the valve may be drawn either hot or cold water.alone, or hot andlcold. water. mixed. in any desired propor- H0115. I Y

To this end, the invention consists of a mlxln chamber with separateinlets from the co (1 and hot. Water. supplies, together. with twovalves, one controlling the outlet fromthemlxing chamber, and the otherthe. inlet to said. chamber from, the hot water supply; the two valveshavinga sliding connectlon wlth each other and a spring tendngto holdthem apart, together with other improvements and combinations of partsset forth claimed hereinafter.

The valve stem R. is slightly convex at its lowerend, as shown at S, and is provided with an, annular flange T adapted toengage a plate U loosely mounted on the stem. The plate 'U' has a screw.connection with a. valve V adapted to: come in contact with the valveseat. N of the mixing chamber To the lowerv end of. he valveV is screwedW adapted to project mixing chamber F; and a. plate Z is loosely mountedon the. extension by the. fiangedheadv Y of a screw X screwed tothe'end" of the. extension. The plate. Z. hasa screw conne'ee tion, witha valve-A. ada'pted'to comein con.- tact with. and close the perforationor valve. seat.

lateral port K, passage-way M and '15 site to'the lateral ing chamber F"an chamber 0, and thence through passages D, but of the ports D and E.The spring B by its pressure on the plate Z tends to retain the valve Aon its seat G, to prevent the entrance of hot water into'the mixing.chamber F, until the valve V and the extension W and screw X are raisedso far that the flange Y of the screw head comes in con tact with theplate Z to raise the valve A. from its seat. When the valve A is raised,

the hot water coming from the inlet 0 and H may-pass through the per-'the passa e foration under the valve A through the port L into themixing chamber F where it will mix with the cold water and flow outwardthrough the opening N If the valve stem is further raised the valve- A"lperforation I in the mix gradually closes it, thus reventing theentrance of the cold water item the chamber J into the mixing chamber IBy this construction, when the stem is first turned, cold water ispermitted to flow through the valve. As it is turned further, the hot.water is permitted to mix with the cold and finally upon the further.turning'bf the valve stem the cold water is shutoff and hotwater aloneflows through the valve. Upon the reverse movement, the two valves V andAare forced downward simultaneously because the spring B tends. to holdthem apart. When, however, the valve AI reaches the valve seat G, thevalveV is still raised from its valve seat, so that the. hot

- water is shut oil" before, the cold water is.

v stem forces the valve V home on its seat,

Further downward movement of the valve and Sbo s the entire flow of thewater through the va ve, and restores the parts to their normalposition, shown In Flg. 1 By means ,of the convex'end Set the stem, thevalve V is seated squarely on its seat, and is held there by. the sprin.B againstrattlmg because as soon ast e valve A is seated the spring Btends to press the valve V upward I against the convex end S of the stemand the further downward movement of the stem presses the valve Vdownward against the tension of the-spring B positivel onto its seat.Furthermore, when the va ve' A is seated, the cold water which isadmitted to the mlxingchamber F will tend to hold the valve A on itsseat. When it is desired to remove the valves "and associated parts, itis only necessary 'to unscrew the part 0 of the casing from the" part A,when the-stem R, valves V and A, and spring B may be removed as aunitary structure, because the opening in the casmg A is wlder than thevalves and the opening N is wider than the valve A. 1
